Menstrual Blood Stem Cells in Poor Ovarian Responders

The menstrual blood of patients in the MenSCs treatment group was collected in sterile menstrual cups on the second day of menstruation, and directly transferred to a class B clean room for MSC isolation and culture. All cell quality control studies were performed prior to the International Conference of Harmonization Q2 (ICH Q2) guidelines. The density of the final product was 20×106 cells/ml. 150 μl of the prepared suspension was injected intravaginally into each ovary of the patient under general anaesthesia
